Laura in Boston says one of the restrooms at her school is a real note bonanza. The inside of the stall features no fewer than four individual notes about proper flushing etiquette, and immediately outside the restroom are two (slightly contradictory notes) about proper door opening/closing procedure.

As we’ve seen this week, notes re: the neighbor’s constantly barking dog often end up being less passive-aggressive and more out-and-out aggressive. But as Matt noticed, this San Francisco resident was able to put a festive holiday spin on the old not-so-veiled threat.

Amber received this amazing note in an envelope on her doorstep in Sacramento. “I have no idea which neighbor sent this to me, but I can only assume it was the paranoid-looking woman who lives above me,” she says. “But I don’t do drugs. I don’t even smoke cigarettes!”
